I was thinking “don’t drop the clutch basket”! 😉
That’s was my thought when he was pulling it.
Me Too!!
yes good idea; Did he find the valve keepers for that dropped/damaged wedged valve?
Yamahahaha
Did that with my DT125 in 1987, 16 years old, couldn’t afford a new one. Drove it daily for two years with that broken basket, never had any problems 😃
I have one of these, I bought it for $600 the kid that sold it didn't know how to fix it and this is actual how I found this channel. The dip stick only works if you run it for 5 mins, and it seems like it is common for people to over fill the oil because of this it takes 1.3L. One of the things with this model, the valves need adjusting often I have heard. I haven't had mine long enough to know yet.
Good call. Most bikes with oil in their frame have a similar check procedure.
Don’t be scared to adjust the valves, it’s easy and well worth it. I can hear valves out of adjustment from a mile away lol.
Joe, I think like you alluded to early in the video, it was probably running lean. The lean condition caused the valves to run hot and then they failed. That carb was pretty gummed up. I bet the valve dropped because it was red hot and then broke. My $.02.
Definitely could be!
As a valve engineer, I agree. It's a 1 piece forging beyond the point of failure, so most failures here are due to overheating. It can be caused by insufficient lash, but that's rare with an aluminum head since it will gain lash as it warms up.
He mentioned they did a valve adjustment and it locked up after that
The valves are titanium i would say it was a bad adjustment
Even a really really bad adjustment the valves won't smack the piston. It was out of time. The sellers never lie! Haha
@@ctbale1 That's what I think too. Out of time.
I think he was lying about the $2100. Why would he sell it for $500 less than what hes being offered? Maybe he just wanted to meet the famous 2vintage.
I just sold one and had to take a $400 loss🤷🏻♂️
He not famous 😂😂.
@LM-id1bb I don't lower the price on anything what I have it listed for is what it is.
Who cares!
@@LM-id1bb if it doesn't sell goes out to the field and rusts away.
Gotta love those 'I got someone offering me more money for it' after you already agreed to a price/deal. There is no better offer...it's a common ploy to get more money out of an interested and emotionally attached buyer. Pretty trashy thing to do also. This has happened to me so many times at this point. Now, just to punish this 'scam' I've started backing out of the sale when they do this. I tell them to take the better offer and that I would feel bad if they sold me to me for less. Usually the item is still for sale weeks later. Then I offer them less than my last offer. Sellers - Don't be trashy. If you agreed to a deal for a price, honor it and don't try to pull this crap.
That's the tactic I use. It's been on sale for weeks....... here's my offer & I understand if you don't take it.
Don't back out, just lower the price and say "call me back when you are ready to sell it for this (lower) price."
I agree 100% sellers honor your word, if you agree on a deal, stick to the deal
This will be the 3rd time mentioning in your various videos that Millennium Technologies right there in Wisconsin can fix that head and they do cylinders as well.
The way that antifreeze was draining, I was expecting a shake at the end! 😂
Replace the valve seat, smooth out all the rough high spots to stop pre-detonation. Usual cause of valve drop is spring seat pressure too light allowing the valve to go into orbit making contact with piston or as I always said to my machine shop clients. Mr. Piston, meet Mr. Valve. Ain't it a fine how you doin'?
Pressure test the jug for water tight, then cut out the seat, replace with new seat, grind it nice and smooth for the valve, same for others, replace springs with heavier springs. It also doesn't take much chain stretch on these 5Valves to cause valve interference.
Love to just sit in school and wait for 2 vintage to post 🙌🏼
😂Same, admin at a university, working on class schedules on one screen 2vintage on other
Just a thought but it might have over revved and floated the valves since more than one valve is bent. To clean the carb use vinegar. Sit all the dirty parts in it including the jets. It will soften the brown stale fuel and you can just wipe it out. Won't take long.
it is very common for dry sump systems to show no/low oil on stick if they been sitting a while. the oil slowly leaks past the check ball in line and it all sits in engine until is started. it will then pump back into oil tank. this is why is always recommended to start and run engine a few minutes before checking oil level or you can grossly over fill system.
Wasn't all that much oil in the case either as seen when he drained
That's a bummer. I'm a sucker for those 5 valve Yamahas. I prefer them with stainless valves though
Yeah because yamaha doesn't know ss is better than titanium.....😅 People just never cease to amaze me
@@michi_danksta I usually don't respond to comments like this but people never cease to amaze me by their cynicism. When I get an old bike like this I replace the valve with the available ss valves because most of the time the ti ones are tired. Of course you have to get the proper springs for the heavier ss valves but they usually don't snap like the ti such as this one did but alas I must be a person that amazes some people using their head as a suppository. It is my preference to do this. Get off your high horse
Check the fly wheel key. The engine stopping that fast might have damage it.
In CA a dirt bike with a plate usually brings about $1000 more than the same or similar bike without a plate.
You need one of those cameras so you can see inside the cylinder would be a great investment for you
most likely titanium valves.. Looks like the oil filter did its job, filtering the metal flakes to where they could not be spread around.
why do people treat their motorcycles like this? obviously over revving it.. the carb is all plugged up, seriously people.. treat your things better.
thanks for resurrecting another one Joe. I wish i had bikes near me that were available for cheap.
I watched the 400cc vid of this last night... I had to check both vids 3 times to make sure it wasn't the same😂😂😂 love watching bro
I've got a 1978 husqvarna 390 wr two stroke , street legal. Awesome find !!!!❤
I have a box of vintage parts with some 390 wr parts in it 😅
Suppose the. Valve adjustment was on the small ish side and no spin over heated
Its a dry sump system. It has to run for a few minutes then sit for a bit on a level surface then check.
Yes like the DRZ-400
He should know this by now, he should know a lot more but persists with bad practices
@@bananabrooks3836 -- Let me guess . . . single?
@@bananabrooks3836 zing 😳
my favorite "vintage" channel
You do a great job at filming and showing everything with detail from start to finish. Great channel!
I wonder if the buddy that adjusted his valves may have mixed up some shims or something. I know you'll set them right after the reassembly!
Check and keep those good valves and cups.
That bike would definitely be worth fixing, the on road title is just an added bonus!
I’d say a good machine shop could save that head. All depends on how much a 2nd hand replacement would be. Two new seats, a bit of tig work and your up and running.
I hope he tries this just to see if it will work out. But i kinda feel like its one of those things that wont ever be right. Also concidering the valves seem to be a weak point of this rig.
Junk the head not worth the headake....
Benny cracks me up bouncing around wanting to play
You mean Vinny?
@@ericball6894 it's either Vinnie or Vinny. Joe has never told us about how his name is spelled.
I call him Joe's "Master Mechanic"😊😅😂
I like how he sniffed at motor then lost interest,like yup dad this one is a dud!!!!funny😊😊😊
@@allensnook7760 Vinny/Vinnie keeps us amazed!
@ericball6894 sorry I thought he said benny
@2vintage the wr250f and crf250x are very popular over here In England, average wr price 4/5k , enjoying your blogs and learned a few things .👌
2 stroke mechanic lover, but loving the 4 stroke videos.
Suspiciously clean top end cases
You are meticulous in your work
Pleasure to watch.
Great content
IF it is vinny approved ... you know it will work out well....maybe the valve was defective ? Fastheads has new head with stainless valves ...Millenium might be able to weld and fix the head ? I guess Vinny was wrong this time ...
Always makes carb removal or install easier if you heatgun the manifolds .
That was a nice thorough diagnosis on the bike. Can't wait to see it rip.
Really interesting watching your skill of a mechanic 👍
Cool video, great troubleshooting skills. those are titanium valves, the wr 450 are notorious for this problem. valves are so hard they can drive the seats in causing the keepers to fall off if they're not adjusted right away... my buddy put stainless vales in when the head was redone if remember correctly. there is a place in Southern California that can fix that head but the company name escapes me. its been 20 years or so....
Can’t wait to see this rebuild, and running again had one similar to this myself wich was 2001 (got stolen never seen it again hate bike thieves) very clean for its age. Looking forward to the follow up video. Love your work and videos bro. 💯🤙🏻
Congrats on 400k subscribers. 💪👍
Or just maybe, they guy was blowing smoke by telling you people wanted it for 2100.00 . Good on you for calling him on it. LOL
Joe, when you measure the piston, hold the calipers horizontal to the piston, you will get a truer measurement.
Have a good look at the right side of the crank at the connecting rod pin. It looked discolored/blue, like it had gotten really hot, unless it was just shadows and the camera angle.
Just from the very beginning that thing is SO clean!!! SUPER clean!! Oh I hope you get it working, STREET LEGAL? That's AWESOME
edit: darn Joe I think the first thing i'd do (I'm 4 minutes in and I do NOT seek forward to see how the video goes) but man I'd absolutely have to put that thing into gear and push it a little just to see, I'd have to know why that kick starter isn't moving.. it seems crazy it would be blown, but who knows.. I can't wait to see!!
Valve drop on WR is common , my WR450 went the same way, had to replace head an valves on mine here in 🇬🇧
WR is road legal enduro here in uk with electric start common bike here
YZ is motocross again in uk same motor in both
I don't know if the early WR250 transmissions have the common worn 5th gear dogs / shift fork as the 400's and 426's, but you may want to split the cases check that before reassembly. My 2001 WR426 has that problem. I know it's a very common issue. It will feel like a slipping clutch in 4th and 5th towards the higher RPMs. The dogs on the gears round out, or the shoft forks bend making it feel like the clutch. Jerky and slipping or commonly referred to surging. Also, Titanium valves. they hate to bend like any other valve, except titanium is very brittle. Also, I was given a registration from dealer and DMV in NJ when purchased new, even though title says "offroad use only."
Just went through my machines in storage and found something I'd forgotten about. It's an air compressor for Flamethrowers. It's 2 stroke powered and maxes out just over 3,000 psi. It was last serviced during the Korean war. It was thrown out because the engine seemed to be seized, but it just had gravel jammed into the cooling fan on the crankshaft. Going to work on it a little and try to find a use for it. I could use it to provide pressure to the large caliber air rifles, maybe use it to cut metal with high pressure water jet, a home made flame thrower... Any suggestions?
Sounds like nobody could care less about what you got going on over there on the other side of the glass and had to tell someone. Well today is your day and I heard ya big guy. Sounds awesome and keep it up and you will have yourself something nice over there in no time 👍
@@kingyankee69 , did you think I was ringing the dinner bell for trolls? Sorry, but my question was for Joe.
@@sandmanbub😂😂
The bike needs new tires too. Knobbies ain't a good choice for asphalt and are probably illegal in Wisconsin. Had to run street-n-trail tires on the street legal enduro I had in high school.
Used WR250Fs are very hard to come by and they command high prices. I just broke down after looking for a used one for years I bought a new 2024 WR250F. Street legal conversions are pretty common with these bikes and that does add to the resale value. I live in Tennessee and it's fairly easy to convert and title the WR250F here so I probably will do it.
Love your videos! A bike lift would make your projects go a lot easier on your back!
I think you should get into flipping motorcycles! I know you have done a few. Love your vids!!!!
Yes correct to check oil after run 5 mins and then let sit 1 minute.
Dont screw cap in when checking.
Just set on threads.
Still lots for this young man to learn about bikes.
But he's doing pretty well❤
love the build cant wait tell the next one on this bike thanks for the videos.
These 01s are known for weak big end bearings. They were smaller than later years and didn't get enough oil if the oil wasn't maintained good. Titanium valves too which haven't been known to age particularly well over years of abuse.
Running it wide open,on streets and hiways cant help.
42:01 Don't drop thAT CLUTCH B A S K E T ! ! !
🤣😉
100% worth more being street legal. People just dont know how simple the process actually is to plate a dirtbike.
Let add.....its not cheap, but simple
I watched your vid. You never pulled the buckets before pulling the head. You would of seen the valve dropped. Not to mention cataloging the size of shims to what valves would of helped understanding why. Another thing is the timing looked synced correctly from dots on EX to IN being close enough to TDC. The one intake valve that dropped could of been a little over shimmed (too big of a shim). Once verified all but one valve was bent tells me timing was off and that since cam timing looked good or close you should of checked the flywheel woodruff key for being sheared. You didn't do that and should of checked that in the video.
P.s. order a new cam chain also.
Thats a nice bike man I still have my 01 yz250f I love it its super clean I picked it up for 800$ with the title ive had it for 3 or 4 years still runs great but I recently took it apart an put a new timing chain in and now it's hard starting and running ruff the old timing chain was really bad definitely needed it im thinking now it's got a new chain the valves are probably off
So lucky that the valve was stuck in that port and didnt just fall in and destroy everything!
Weld that valve inlet shut and run it as a 4 valve.
More Vinny ! 🐕 Good stuff man.
Joe, please please please sell us some of these machines.
Dry sump engines will almost always have no oil in the tank if it has been sitting a long time. You could have the seat replaced and grind the damaged head smooth, but it's probably easier to buy a new or used head. I am guessing the bike got over-revved, very likely on a downshift.
The dryer sheets is genius, Ima do that to my 125
I use them in my shed at the lake, the mice seem to hate them, also wrap them around any major wire junctions.
No because they’re really good bikes. The WR’s are pretty much collector bikes now those older ones they were awesome they’re even wicked bikes today the 2023 I have one and the thing is amazing. I love it. Yamaha have always made amazing bikes.
This what happens when you adjust and don't know what your doing. It's a shame
I totally agree
I totally agree
You can advance intake cam 1 tooth , chop grey wire to cdi , unclip white cover off airbox n cut out the round indents in the black part of the inner airbox behind white cover then obviously go up jet size tune air fuel throw on n aftermarket silencer then you have a regoed yz mate
Need to find out why the valve dropped. It might of been brittle but I think is was not hardened correctly
You should get a step stool for unloading the bikes. It'll save your back one day.
Sound advice. I blew up two discs in my back trying to lift my son's three wheeler into a pickup. The surgeon ended up butchering the job and now I'm pretty much useless. People learn from my mistake - never lift heavy objects by yourself. Ever.
I keep telling him to get a bike lift but he never does...
You can't put an old head on young shoulders - and you can't put a new spine in an old mechanic...
🤣
Same goes for knees....
That heads 100% repairable .
Remove valve seat . Weld damaged area.
Remachine
Install new seat.
Check guide and then a valve and seat regrind .
New valve.
Its the cost to repair that may be more then a good used head.
Watching that coolant drain reminded me of pissing at 3am in the middle night ! Lol
Did my first oil change on my bike. I now it’s nothing big but you gave me the confidence do to it. Love the videos as always joe.
We all have to start somewhere. 👍
@@paulbudford that’s true. Thanks 💪🏼
The titanium valve the Yamaha uses are machined in 2 pieces. Cheaper to make. They use a bonding process to connect them. That is exactly where they fail. Stainless valves don't have this issue. you lose a little performance. but gain longevity
Get rid of the titanium valves and go for steel kibble whites with new springs, you'll have less tolerance issues and they'll last longer than Ti
That hardened black shit is why you never run ethanol fuel, especially in EFI bikes
I feel bad for the seller back in 2016, dude just got the bike fixed up (looks immaculate inside besides the head and piston). And his friend decided to not adjust his valves properly.
Ya the frame is street legal so it makes it desirable as you can do what ever like change motor and it’s still legal. The frame is what gets the street legal label.
Long way from you but Rams Head Service could fix that for sure. Fixed a couple of torched nitro harley heads for me way cheaper than replacement cost
The head is repairable and the piston is good
I was just about to say. The head could definitely be welded up if anything and be machined to spec. Piston could be saved but cheap enough to replace it.
Definitely not really worth saving might as well buy new
for how much $ ?
The pristine-looking oil and coolant pointed to neglect. The oil varnish sounded the neglect alarm. Fresh oil doesn't do that.
I remember when these bikes were new in the shop and if I'm not mistaken they were going for almost 8k brand new
Yes ,around $7,600 retail ,quality machines I hear, good power 🔋
So the owner said it HiT -n- Quit..... had it run any longer wouldn't the broken parts have damaged/destroyed the cylinder? I only
ask b/c I'm not a mechanic but this is a good place to learn. Thanks for that, peace
This guy is brilliant at what he does
Sorry for the bad luck on this bike Joe. But once it’s rebuilt by you it is going to be a really nice bike for years to come for you
Surprised to hear theyre rare in the US, here in Oz theyre very common. I had a 2001 wr450f back in 2006 locked up aswell and it cost 2k AUD at the time which is about $3 US 😂
sick bike! so close to 400k!
This is why they are so rare for the street...Maintaining the Yamaha WR250F is a little intense. It has 1800 mile (3000 km) maintenance intervals at which you need to change the oil/filter and check everything other than valve clearance. Then every 3000 miles / 5000 km, you check the valves. Not a great bike to be running on the street.
The steel frame wr’s have a dry stump so you won’t get any oil on the dip stick since it hasn’t ran they need to run for a few minutes then be checked for the oil height
Stop at Harbor freight and get a borescope camera to look in the spark plug hole. its fun watching your vids
PC high compression piston and then Millinium technologies can save that head for cheaper than a new one, while doing extra port work. I'd send the cylinder off too for porting and polishing, it's cheap as an add on service.
I have a '99 WR400F very similar, street legal, fun bike!
I havnt watched all the video yet .
But i have this bad feeling the last guy over shimmed the valves and cause it to hit piston while doing valve clearance 😬
Its a fairly involved process if there out of tolerance
Win some lose some, that bikes in really nice shape for an '01, it's definitely worth putting the money into.
I want a newer fuel injected WR. I noticed they don't come up for sale too often but the older ones like this one does. Many of them are clapped out and around $2500 and needing "tlc".
I struggle to understand why you'd pay 1600 for a seized bike. This would be less than $1000 aud here in Australia. 4 strokes with engine issues aren't worth any more. You end up $3k to 4k into the things plus the work. They don't sell for that here that age, even if rebuilt.
Send the head to Millennium technologies. They’re right by you in Wisconsin. Buy all new OEM valves and they will set you straight. Do it right and don’t buy a used head.
That would be interesting to see if that head could be fixed. Probably could get away with reusing the good valve too
@@ctbale1 a used valve on a new head is not a good idea. I don’t doubt the head has 100 hours plus. Used valves with hours on them have caved in edges. If he were to lap it in to a new head that valve seat is that much closer to needing a new seat again. He will fill find himself shimming that valve and only that valve very often until he runs out of shim sizes (of course all depending how worn that valve is)…it’s best to get all new valves. Like I said in my original comment doing it right is important. The bike world isn’t fair…work costs more than the actual bike. That’s why a lot of guys cut corners.
@@motion_mx I think I qualified my suggestion towards flipping it.
I had a 2003 yz250f. Hated that thing. Endless problems. Got rid of it as soon as I could
There won’t be oil on the dip stick till the bike is running, I thought the same thing when I bought my 2003 yz450 lol
I think you could save it get Valve cutting kit try to find a kit with the same valve size it just cut in it a little bit
Titanium valves that are friction stir welded will often break at the head to stem joint. It seems to happen more often once the valve faces get cupped, but I've seen several break for no apparent reason too. I much prefer bikes with stainless valves, even if they don't rev quite as high or quickly.
Try Del West valves. Never let me down even at Baja.
Il be watching the duration of this vid with a kean eye throughout the day whilst I'm supposed to be at work 😂. I had a 2002 WR 250f which I loved, however that oil drain plug on the frame you pointed out there vibrated loose whilst I was riding mine.. This bolt came loose for no more than a minute or so before I realised, however this was enough for mine to need an engine rebuild... Which cost me over £500 15 years ago haha. When I got the bike back it still had a rattle unfortunately. I then sold the bike for next to nothing 😞.
Need to run the stainless steel valves...also I think Millennium Technologies might be able to repair the valve seat area if the head for you...they work miracles
That would make a great DS to tool around on
Mouse repellant on the cheap! Dryer sheets work well for such duty.
